Bonjour,

Exercice 13 :

a) 183,9 = 1,839 * 10^2

b) 6047,8 = 6,0478 * 10^3

c) 0,021 = 2,1 * 10^-2

d) 0,453 = 4,53 * 10^-1

e) 75002 = 7,5002 * 10^4

f) 57,4 = 5,74 * 10^1

Exercice 14 :

A = 36 * 10^1

A = 3,6 * 10^2

B = 0,07 * 10^-4

B = 7 * 10^-6

C = 7091 * 10^5

C = 7,091 * 10^8

D = 285 * 10^2

D = 2,85 * 10^4

E = 528,15 * 10^3

E = 5,2815 * 10^5

F = 95,6 * 10^-1

F = 9,56
